Force

Forces can be applied in different directions.

• TRUE

• FALSE

Force depends on

• Force

• mass

• acceleration

• mass and acceleration 

8 N to the left , and 4 N to the right. Find the net force. Is this balanced?

• 12 N Right;  No

• 4 N Left;  No

• 12 N Right;  Yes

• 4 N Left;  Yes

Which one is balanced?

• top

• bottom

• both

• neither

If there are two forces going in the same direction how would you find the net force?

• Subtract

• Add

• Neither

• Multiply

Find the net force: 15 N to the right, and another 15 N to the right.

• 0 N Right

• 0 N Left

• 30 N Left

• 30 N Right

You and your friend are playing tug of war. Your friend pulls with a force of 55 N to the right. You pull with a force of 65 N to the left. What is the net force on the rope?

• 10 N left

• 20 N

• 10 N right

A force that resists the motion of two surfaces sliding across one another

• Gravity

• Magnetism

• Friction

• Position

Objects that have more mass also have more gravity.

• True

• False

An example of the force of gravity is-

• a rocket flying through space

• a ball falling to the ground after it has been thrown

• a cloud moving across the sky

• the Sun rising
